FRANKLIN M. BAR'NARD, OF MILFORD, IOWA.

SAW-JOINTER.

To all whom it may concern:

Be it known that I, FRANKLIN M. BAR- NARD, a citizen of the United States, and a resident of Milford, in the county of Dickinson and State of Iowa, have invented a new and useful Improvement in Saw-Jointers, of which the following is a specification.

My invention is an improvement in saw jointers, and has for its object to provide a jointer of the character specified, of such size and compactness that it may be carried in the pocket of the user, and which will always be ready for use, and which may be used on any type of saw.

In the drawings :Figure 1 is a side view of the improved jointer in engagement with a saw, Figs. 2 and 3 are longitudinal sections at right angles to each other, and Fig. 4: is a perspective view of the bolt.

The present embodiment of the invention comprises a shell 1, of cylindrical form and of suitable thickness, and the said shell is provided with oppositely arranged alined openings 2, in its side wall. The openings 1 2 are near one end of the shell and the said shell has a longitudinal slot 3, extending from each opening to the end of the shell remote from the opening. The slots 3 are of considerable width and each opening 2 has a notch or recess 4, at the opposite side of the opening from the slot and in alinement therewith.

A bolt comprising a head 6 and a stem 7, is arranged within the shell. The end of the stem 7 remote from the head is threaded as shown at 8, and the head is providedwith a transverse opening 9, and with the slot 10 leading fro-m the opening to the end of the head remote from the threaded portion of the stem.

The opening 9 is so arranged that a transverse shoulder or ledge 11 is provided at each side of the slot 10, and between the said slot and the adjacent side wall of the open ing 9. The head 6 of the bolt fits the interior of the shell loosely and a nut 12 is provided for engaging the threaded portion of the stem, the said nut being of approximately the diameter of the shell so that the said nut will bear against the end of the shell to clamp the file 13 in place in the openings 2.

The stem is arranged in the shell with the head toward the notches or recesses 3, and with the threaded portion of the stem extending through the opposite end of the Specification of Letters Patent.

shell. The file 13 is arranged in the openings 2 and in the opening 9 of the head, the said file being a three-cornered file.

The file is arranged with the base thereof parallel with a plane extending transversely of the shell and with the edges of the said base resting on the shoulders or ledges 11 of the head. It will be evident that when the nut 12 is turned in the proper direction the file will be clamped between the said shoulders or ledges 11, and the opposite side of the openings 2. The extensions or notches a of the slots 3 are for receiving the apex or angle between the side walls of the file to prevent injury to the said angle or apex when the file is clamped in place.

In use, the device is arranged as shown in 1, with the file in position as above specified, and when it is desired to joint a saw, the file is moved over the points of the teeth, the saw passing through the slots 3 of the shell. The points also pass through the slots 10 of the head, and the points engage nothing but the file. The teeth may be thus jointed evenly and when one face of the file becomes worn another face may be brought into operation merely by loosening the nut sufficiently to permit the file to be turned.

The device is small and compact and with the file removed, may be easily carried in the pocket. lVith the file in place, it is firmly clamped so that it cannot be dis placed by its engagement with the teeth and when any part of the file becomes worn, the file may be shifted longitudinally or turned as above mentioned, until it is completely worn out.

.l olaim:

1. A jointer comprising a cylindrical shell having near one end oppositely arranged alined openings in its side wall and having a longitudinal slot extending from each opening to the end of the shell remote from the opening, said slots being in register for permitting the passage of a saw blade, each of the said openings having a notch at the opposite side from the slot and r the stem, and adapted to register With the slots of the shell, said head having a shoulder at each side of the slot, the opening be ing adapted to receive a file With one face 5 thereof engaging the shoulders, and means engaging the stem for clamping the file in place. I

2. A jointer comprising a shell having oppositely arranged alined openings in its 10 "side Wall near one end and a longitudinal slot extending from each opening to the opposite end of the shell, a clamping membet or a file comprising a head having a transverse opening adapted to register With the openings of the shell, said head having a stern extending beyond the shell at the end adjacent to the opening, and having a slot leadin from the opening to the 0ppo site end 0 the head, said head having a shoulder in the opening at each side of the slot, and means engaging the stem for drawing the head longitudinally of the shell.
